I don't often post but I am a faithful reader and have learned so much about our furry friends. I am also entertained by the many ferret antics and saddened when one of our friends must leave his/her human friend behind on this earth, even if it is temporary. I just want to add something about the two drugs (Ivomec and Dectomax) that were discussed. Both of these drugs are macrolide endectocides and are used for many parasitic skin infestations and some internal parasitic infections. However, they are not the same drug. Ivermectin is the generic name for Ivomec, Eqvalan, and Heartgard 30. These are trade names used by various manufacturers. (The human counterpart of Ivermectin is Mectizan Ivomec) The generic name for Dectomax is Milbemycin Oxime. Other trade names for this include Interceptor, Moxidextin, Cydectin, Doramectin, and Abramectin. However, the indications for both drugs are the same. Also, it would appear that both drugs use pretty much the same mechanism of action which is too long and technical to go into. As far as availability of Doramectin in the United States, I do not know. For more information, I would advise to check out the Ferret FAQ (http://www.ferretcentral.org/faq) or http://vet.purdue.edu/depts/bms/courses/chmrx/nemathd.htm I am not a vet but I do have a science degree and have taken several pharmacology courses.
